中文摘要：

为了研究L形截面短肢剪力墙的抗震性能,对6个1/2缩尺比例的L形截面短肢剪力墙试件进行了低周反复荷载作用下的试验研究,分析了轴压比、截面高厚比、剪跨比等参数变化时,对试件的承载力、延性、滞回特性、耗能能力及破坏特性等抗震性能的影响。结果表明：L形截面短肢剪力墙试件扭转变形较小,试件以弯剪破坏为主,腹板底部为试件最薄弱部位,剪跨比小,轴压比大的试件腹板中心剪切破坏现象明显;试件随着截面高厚比、轴压比的提高,极限承载力增加,试件耗能能力变差、延性下降明显;L形截面短肢剪力墙试件在截面高厚比适中,为6.5∶1时,经济、抗震性能也较好。

英文摘要：

To study the seismic performance of short pier shear walls with L-shape section,the experiment of six 1∶2 scale L-shaped short pier shear walls subjected to low cyclic loading are conducted.The influence of axial compression ratio,sectional height to thickness ratio,shear span ratio to the bearing capacity,ductility,hysteretic characteristics,energy dissipation capacity and failure mechanism of the short pier shear wall are analyzed.The results show that the torsion deformation of specimens are small,specimens mainly reveal bending-shear failure modes,the bottom of web is the weakest part of specimen,and the shear failure appears obviously in the middle of web in specimens with small shear span ratio and big axial compression ratio.The ultimate bearing capacity is increased,energy dissipation capacity is turned to worse,ductility is obviously decreased with the increment of sectional height to thickness ratio and axial compression ratio.The specimens are economic and the seismic performance is better too when sectional height to thickness ratio is moderate,for example,is 6.5∶1.
